go doc

  • Display doc for current package: go doc
  • Display doc for type in current package: go doc TYPE or go doc -all TYPE

go test

Run all tests:

  • Run all tests: go test ./...
  • Run all tests in package: go test modulename/pkg/packagename/
  • Run all tests in file: go test path/to/file_test.go

Run subset of tests:

  • Run function tests: go test path/to/file_test.go -run FUNCTION_TEST_NAME
  • Run a single test in function tests: go test path/to/file_test.go -run FUNCTION_TEST_NAME/test_name_here

Tips:

  • Skip test caching with -count 1.
  • Run tests multiple times with -count 10. Useful for finding flaky tests.
  • Add -v for verbose output. Useful for finding test names and whatnot.
